BOTTLE.

Specification of Letters Patent.

Patented June 25,1918.

Application led .Tune 27, 1917. Serial No. 177,385.

7 1o all whom it may concern:

Be it known that I, HENRY E. LnN'r, a citizen of the United States, residing at Park Rapids, in the county of Hubbard and State of Minnesota, have invented a new and useful Bottle, of' which the following is a specification.

My invention relates to bottles, and the object is to provide a bottle of such construction that it will serve not only as a liquid container but can also be used to deliver its contents in doses or equal quantities. Another object is to provide a bottle which will not spill out its contents it' falling on either side while its cork is removed.

I attain these objects by the construction of a bottle as shown in the accompanying drawing, in which:

Figure 1 is a side elevation of a flat bottle, with one side wall cut away as on the line a-a; in Fig. 2. Fig. 2 is a vertical sectional elevation of the bottle as on the line b-b in Fig. 1.

Referring to the drawing by reference numerals, 1, 1a, designate the side walls, 2, 2x1 the narrow or edge Walls, 3 the bottom, and 4 the top portion of a flat bottle such as are most used for medicine.

l/Vthin the bottle are several chambers; a main or containing chamber 5, a measuring chamber 6, a dose chamber 6, and a pouring chamber 7, 71. The latter forms also the neck of the bottle and is provided with a cork 7b. Said chambers are formed between the walls of the bottle and partitions 8, 9, 10, 11 and 12, some of which incline as shown. 13 is a cork to remove when the bottle is to be filled.

In the partition l1 is a port 14 near which there is an inclined guard 15. And in the lower part of the partition 9 is a port 16, which is normally open but if the bottle be inverted or nearly so, said port is closed by a gravity valve 17 which is loosely fitted to slide in a vertical valve chamber 1S, from which a port 19 opens into the chamber 7. In the manufacture of the bottle, if' it be found difficult to make the valve chamber with solid bottom and the valve plug loose withinit, the chamber may be open at the bottom and the bottom of' the bottle may have an upwardly bulged portion 20 with a hole and cork 21 therein, so as to admit a suitable tool for grinding the valve seat in the port 16, and then place the valve in the chamber and close the bottom thereof by a cork 22, which cork may also bc employed to regulate the stroke of the valve, and after this is done the cork 21 is secured in place. But as already stated, I do not mean to confine the form of the bottle to the use oi the corks 21 and 22.

Usually large bottles are used for medicines taken in large doses and small bottles for medicines taken in small doses and hence the sizes of the chambers may vary with the sizes of the bottles.

In the use of the bottle for filling prescriptions, if for instance the prescription calls for a dose of two drams, the medicine is then put up in one of these bottles having a chamber 6 large enough to hold two drams. In pouring a dose of the medicine from the bottle into a spoon or cup preparatory to giving it to theI patient, the bottle is first inverted until the chamber 6 is filled with medicine through the port 14 while the air escapes from said chamber into the main chamber 5 through said port 14. lVhen the liquid reaches as far as to the line 23 the measuring chamber 6 is full and the bottle is turned bottom downward so that the measured dose will escape through the port 16 into the chamber 7. The bottle is then sufiiciently inclined to pour the liquid out at the neck 7 a'lter the cork 7b has been removed therefrom. While thus tilting the bottle to pour out the dose the next dose will fill into the measuring chamber 6 and be ready for next time not that it remains in that chamber very long, for as the bottle is righted the second dose runs into the chamber 6a and thence through port 16 into chamber 7, where it remains until it is to be removed from the bottle.

The shield 15 serves to guard the port 14 so no part of the measured medicine can escape from the measuring chamber into the chamber 5 but must pass into the chamber 6a as a temporary container until the dose has had time to pass through the ports 16u19. The latter ports, whenever the bottle is partly or fully inverted, are closed by the gravity valve 17 so as to prevent accidental escape of any part of the dose from the chamber 7 back into the chamber 6.

It will be understood that if a bottle of this construction should happen to be turned over upon either one of its two main sides while the cork 7b is removed, hardly any of' the medicine in chamber 5 can escape from the bottle even if the bottle is almost full. rl`hus if the bottle in Fig. 2 be turned with the right hand side down the liquid could hardly reach up to the port 14 and escape therethrough; and if the bottle falls to the left and rests on that side the liquid could not reach ,high enough up to escape through the port 16 after it got into the chambers G-G W'hat I claim is:

1. A bottle having in its upper end an outlet duct and means for closing the same, and below said outlet duct and communicating therewith a pouring chamber, and at one side of said outlet duct a measuring chamber having a side port through which to receive liquid from the contents of the bottle when the latter is in an inverted position, and a dose chamber forming an extension of the measuring chamber and being of a size to hold the measured dose when the bottle is in upright position; said dose chamber having in its bottom a port leading into the pouring chamber and a gravity closed valve arranged to close vsaid port when the bottle is inverted.

2. A bottle having in its upper end an outlet duct and means for closing the same, and below .said outlet duct and communicating therewith a pouring chamber, andat one side of said outlet duct a measuring chamber having'a side portthrough which to receive liquid from the contents of the bottle when the latter is inA an inverted position, and a dose chamber forming an extension of the measuring chamberand being of a size to hold the measured dose when the bottle is in an upright position; said dose chamber having in its bottom a port leading into the pouring chamber and a gravity closed valve arranged to close said Port when the bottle is inverted, said port from the main bottle to the measuring chamber being y disposed near one side of the bottle and the port having 'the valve being disposed near the other side of the bottle.

3. A bottle having in its upper end an outlet duct and means for closing the same, and

below said outlet duct and communicating therewith a pouring chamber, and at one side .of said outlet duct a measuring chamber having a side port through` which to receive liquid from the contents of the bottle when the latter is in an inverted position,

and a dose chamber forming an extension of the measuring chamber and being of a size to hold the measured dose when the bottle is in upright position; said dose chamber having in its botto-m a port leading into the pouring chamber and a gravity closed valve arranged to close said port when the bottle is inverted, and a special opening in the top of the bottle for filling it, and means for closing said special opening.

4. A, bottle having in its upper end an outlet duct and means for closing the same, and below said outlet duct and communicating therewith a pouring chamber, and at one side of said outlet duct a measuring chamberhaving a side port through which to receive liquid from the contents of the bottle when the latter is in an inverted position, and a dose chamber forming an extension of the measuring chamber and being of a sizeto hold the measured dose when the bottle is in upright position; said dose cham'- ber having in its bottom a port leading into the pouring chamber and a gravity closed valve arranged to close said port when the bottle is inverted, and a fiXed shield guarding the port between the main space inthe bottle and the measuring chamber, to prevent the measured liquid from splashing back into the bottle when the b-ottle is being` righted to normal position.

5. A bottle having in its upper end an outlet duct and means for closing the same, andl `of the measuring chamber and being of a size to hold the measured dose when the bottle is in upright position; said dosecham ber having in its bottom a port leading into.

the pouring chamber and a gravity closed valve arranged to close said port when the bottle is inverted, said bottle having in its bottom an upward bulge with a hole andl a stopper therein, and said valve vchamber having in its bottom an opening and a stopper therein.

In testimony whereof l affix mysignature..
